   Summary

   “What do you think it is?” Senku asked.

   “I have no idea”, Gen said honestly. The glass thing in Senku's hand looked like a phallus but Gen didn't want to say that out loud.

   “I think you do. You're just making it too complicated.” Senku cackled at him, when Gen started to blush furiously.

   “You mean to tell me that you have made a glass dildo just for a gag?” Gen exclaimed while putting his head in his hands.

   “It's not a gag.” Senku said calmly. “Borosilicate glass is one of the few materials that can be used to make body safe sex toys."
